Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time temperature measurement is implemented in the target submarine cable factory joint, then temperature control precision is improved, but device complexity increases due to the need for additional measurement systems
Solution Approach 1:
The patent creates a reference submarine cable factory joint that replicates the structural and environmental characteristics of the target joint. Temperature measurement systems are installed only in the reference joint, copying its temperature field behavior to infer the target joint's temperature without direct measurement. This reduces device complexity while maintaining temperature control precision through the copying relationship.
2Measurement precision
If temperature measurement devices are installed directly in the target joint, then measurement precision is improved, but the joint structure becomes more complex and vulnerable to damage
Solution Approach 1:
The reference submarine cable factory joint serves as an intermediary object that bears the measurement devices. Instead of installing sensors directly in the target joint, the system measures temperatures in the reference joint and uses this data to infer target joint temperatures. This mediator approach preserves measurement precision while keeping the target joint structure simple and undamaged.
3Productivity
If the reference joint and target joint are placed close together for synchronous heating, then heating efficiency is improved, but electromagnetic interference increases
Solution Approach 1:
The patent applies local quality by differentiating the spatial relationships of the reference and target joints. The joints are positioned at distances that balance two local requirements: close enough to experience similar heating conditions for efficiency, but far enough to minimize electromagnetic interference. This local optimization of spacing resolves the contradiction between heating efficiency and interference reduction.
